TECHNICAL FIELD

The present disclosure relates to an optical imaging lens, andparticularly, to an optical imaging lens having at least seven lenselements.

BACKGROUND

Technologies of mobile electronic products are constantly improving. Asa result, optical imaging lens have developed in different ways. In somecases, there may be a demand for improved imaging quality of an opticalimaging lens. There may also be demands for bigger apertures and fieldof views. Currently, an optical imaging lens used in a mobile phone mayhave an Fno range of about 1.7˜2.6 and a range of field of view about 25degrees to about 38 degrees. Industry designers have faced difficultiesin decreasing the value of Fno to 1.4 or less and increasing the valueof field of view to 38 degree or more.

However, a designer cannot simply reduce the thickness of the opticalimaging lens to achieve miniaturization while maintaining image quality.Designing an optical imaging lens further involves a host of otherconsiderations, including its material characteristic, production,assembly yield, and other production problems.

For a more complete understanding of the present disclosure and itsadvantages, reference is now made to the following description taken inconjunction with the accompanying drawings, in which like referencenumbers indicate like features. Persons having ordinary skill in the artwill understand other varieties for implementing example embodiments,including those described herein.

As used in the disclosures and the appended claims,the terms “example embodiment,” “exemplary embodiment,” and “presentembodiment” do not necessarily refer to a single embodiment, although itmay, and various example embodiments may be readily combined andinterchanged, without departing from the scope or spirit of the presentdisclosure. Furthermore, the terminology as used herein is for thepurpose of describing example embodiments only and is not intended to bea limitation of the disclosure. In this respect, as used herein, theterm “in” may include “in” and “on,” and the terms “a,” “an,” and “the”may include singular and plural references. Furthermore, as used herein,the term “by” may also mean “from,” depending on the context.Furthermore, as used herein, the term “if” may also mean “when” or“upon,” depending on the context. Furthermore, as used herein, the words“and/or” may refer to and encompass any and all possible combinations ofone or more of the associated listed items.

In the present specification, the description “a lens element havingpositive refracting power (or negative refracting power)” means that theparaxial refracting power of the lens element in Gaussian optics ispositive (or negative). The description “An object-side (or image-side)surface of a lens element” only includes a specific region of thatsurface of the lens element where imaging rays are capable of passingthrough that region, namely the clear aperture of the surface. Theaforementioned imaging rays can be classified into two types, chief rayLc and marginal ray Lm. Taking a lens element depicted in FIG. 1 as anexample, the lens element is rotationally symmetric, where the opticalaxis I is the axis of symmetry. The region A of the lens element isdefined as “a portion in a vicinity of the optical axis,” and the regionC of the lens element is defined as “a portion in a vicinity of aperiphery of the lens element.” Besides, the lens element may also havean extending portion E extended radially and outwardly from the regionC, namely the portion outside of the clear aperture of the lens element.The extending portion E is usually used for physically assembling thelens element into an optical imaging lens system. Under normalcircumstances, the imaging rays would not pass through the extendingportion E because those imaging rays only pass through the clearaperture. The structures and shapes of the aforementioned extendingportion E are only examples for technical explanation, the structuresand shapes of lens elements should not be limited to these examples.Note that the extending portions of the lens element surfaces depictedin the following embodiments are partially omitted.

The following criteria are provided for determining the shapes and theportions of lens element surfaces set forth in the presentspecification. These criteria mainly determine the boundaries ofportions under various circumstances including the portion in a vicinityof the optical axis, the portion in a vicinity of a periphery of a lenselement surface, and other types of lens element surfaces such as thosehaving multiple portions.

1. FIG. 1 is a radial cross-sectional view of a lens element. Beforedetermining boundaries of those aforesaid portions, two referentialpoints should be defined first, central point and transition point. Thecentral point of a surface of a lens element is a point of intersectionof that surface and the optical axis. The transition point is a point ona surface of a lens element, where the tangent line of that point isperpendicular to the optical axis. Additionally, if multiple transitionpoints appear on one single surface, then these transition points aresequentially named along the radial direction of the surface withnumbers starting from the first transition point. For instance, thefirst transition point (closest one to the optical axis), the secondtransition point, and the Nth transition point (farthest one to theoptical axis within the scope of the clear aperture of the surface). Theportion of a surface of the lens element between the central point andthe first transition point is defined as the portion in a vicinity ofthe optical axis. The portion located radially outside of the Nthtransition point (but still within the scope of the clear aperture) isdefined as the portion in a vicinity of a periphery of the lens element.In some embodiments, there are other portions existing between theportion in a vicinity of the optical axis and the portion in a vicinityof a periphery of the lens element; the numbers of portions depend onthe numbers of the transition point(s). In addition, the radius of theclear aperture (or a so-called effective radius) of a surface is definedas the radial distance from the optical axis I to a point ofintersection of the marginal ray Lm and the surface of the lens element.

2. Referring to FIG. 2, determining the shape of a portion is convex orconcave depends on whether a collimated ray passing through that portionconverges or diverges. That is, while applying a collimated ray to aportion to be determined in terms of shape, the collimated ray passingthrough that portion will be bended and the ray itself or its extensionline will eventually meet the optical axis I. The shape of that portioncan be determined by whether the ray or its extension line meets(intersects) the optical axis (focal point) at the object-side orimage-side. For instance, if the ray itself intersects the optical axisat the image side of the lens element after passing through a portion,i.e., the focal point of this ray is at the image side (see point R inFIG. 2), the portion will be determined as having a convex shape. On thecontrary, if the ray diverges after passing through a portion, theextension line of the ray intersects the optical axis at the object sideof the lens element, i.e., the focal point of the ray is at the objectside (see point M in FIG. 2), that portion will be determined as havinga concave shape. Therefore, referring to FIG. 2, the portion between thecentral point and the first transition point has a convex shape, theportion located radially outside of the first transition point has aconcave shape, and the first transition point is the point where theportion having a convex shape changes to the portion having a concaveshape, namely the border of two adjacent portions. Alternatively, thereis another common way for a person with ordinary skill in the art totell whether a portion in a vicinity of the optical axis has a convex orconcave shape by referring to the sign of an “R” value, which is the(paraxial) radius of curvature of a lens surface. The R value which iscommonly used in conventional optical design software such as Zemax andCodeV. The R value usually appears in the lens data sheet in thesoftware. For an object-side surface, positive R means that theobject-side surface is convex, and negative R means that the object-sidesurface is concave. Conversely, for an image-side surface, positive Rmeans that the image-side surface is concave, and negative R means thatthe image-side surface is convex. The result found by using this methodshould be consistent as by using the other way mentioned above, whichdetermines surface shapes by referring to whether the focal point of acollimated ray is at the object side or the image side.

3. For none transition point cases, the portion in a vicinity of theoptical axis is defined as the portion between about 0-50% of theeffective radius (radius of the clear aperture) of a surface, whereasthe portion in a vicinity of a periphery of the lens element is definedas the portion between about 50-100% of effective radius (radius of theclear aperture) of the surface.

Referring to the first example depicted in FIG. 3, only one transitionpoint, namely a first transition point, may appear within the clearaperture of the image-side surface of the lens element. Portion I is aportion in a vicinity of the optical axis, and portion II is a portionin a vicinity of a periphery of the lens element. The portion in avicinity of the optical axis is determined as having a concave surfacedue to the R value at the image-side surface of the lens element ispositive. The shape of the portion in a vicinity of a periphery of thelens element may be different from that of the radially inner adjacentportion, i.e. the shape of the portion in a vicinity of a periphery ofthe lens element may be different from the shape of the portion in avicinity of the optical axis; the portion in a vicinity of a peripheryof the lens element has a convex shape.

Referring to the second example depicted in FIG. 4, a first transitionpoint and a second transition point exist on the object-side surface(within the clear aperture) of a lens element. In which portion I is theportion in a vicinity of the optical axis, and portion III is theportion in a vicinity of a periphery of the lens element. The portion ina vicinity of the optical axis has a convex shape because the R value atthe object-side surface of the lens element is positive. The portion ina vicinity of a periphery of the lens element (portion III) has a convexshape. What is more, there may be another portion having a concave shapeexisting between the first and second transition point (portion II).

Referring to a third example depicted in FIG. 5, no transition pointexists on the object-side surface of the lens element. In this case, theportion between about 0˜50% of the effective radius (radius of the clearaperture) is determined as the portion in a vicinity of the opticalaxis, and the portion between about 50˜100% of the effective radius isdetermined as the portion in a vicinity of a periphery of the lenselement. The portion in a vicinity of the optical axis of theobject-side surface of the lens element is determined as having a convexshape due to its positive R value, and the portion in a vicinity of aperiphery of the lens element is determined as having a convex shape aswell.
